Abstract: This annual report of the Institut für Kernphysik (IKP) at the Kernforschungsanlage (KFA) Jülich contains short descriptions of current research carried out by members of our institute and by guest groups frequently in cooperation with scientists of the IKP. The majority of the experiments was performed with the use of the 1ight charged particle beams with 22.5- 45 MeV/amu from our cyclotron. Spin-flip states in $^{48}$ca were studied under conditions of very high resolution at our large magnetic spectrograph 'Big Karl' in collaboration with Santo's group from Münster. Schmidt-Rohr's group from the Max Planck Institut (MPI) Heidelberg has investigated the residual interaction through a $^{209}$Bi(d, $^{3}$He) reaction study at Big Karl. This spectrograph has also been used for a test of the Born approximation for the description of the electron transfer in the $^{3}$He$^{++}$ + C + $^{3}$He$^{+}$ + C$^{+}$ reaction. Big Karl has furthermore allowed measurements at angles as low as 1.5° for detailed multipolarity assignments of giant resonances. Theseries of studies on giant resonances carried out in collaboration with the MPI-group from Heidelberg was supplemented by a measurement of the decay of the E2 giant resonance of $^{24}$Mg. Gamma-ray spectroscopy at the cyclotron gave evidence for h$_{11/2}$ neutrons to be responsible for backbending in $^{134}$Ce and for a transition from deformed shape to sphericity in $^{133}$La. Through the measurement of the E3 speed of the 1.57 MeV transition in $^{147}$Gd, the two-phonon octupole character of the 2.57 MeV level was confirmed in quantitative agreement with the expected strength. The $\pi$h$_{11/2}$ + vh$_{9/2}$ GT-decay of n-deficient Tb isotopes vtas investigated for obtaining spectroscopic information about the N = 82 gap in $^{146}$Gd. [...]
